UNITED STATES r'TIT OFFICE COMPOSITE CONTAINER Victor Hendrickson, Los Angeles, Calif. Application August 22, 1939, Serial No. 291,317

2 Claims. (.Cl. 229-55) This invention relates to improvements in containers, and more specifically to composite containers in which the body is constructed of fibre and the top end closure of metal.

All commercial composite containers with which I am familiar are so constructed that the connecting means between the walls of the bre body and thev metal top end closure causes a channel or groove to be formed in and around the end closure. Such a groove or channel has prevented the extensive use of this type of container for the packaging of merchandise of the kind which is placed on display, such as talcum powder, household drugs, and other powdered substance, for the reason that dust and dirt accumulate in the grooves or channel which cannot be easily wiped away, thus imparting an untidy and unsightly appearance and unsanitary condition to the container. It is therefore the main object of this invention to provide a composite container in which the top metal end closure is attached to the fibre body in a novel manner to eliminate any dirt collecting channels in the end closure.

Another feature of the invention resides in a composite container in which the peripheral edge of the metal and closure is interlocked with the top of the bre body to provide a smooth surface throughout the area of the top end closure.

A further feature of the invention is the provision of a composite container in which the novel interlocking parts between the metal end closure and the libre body may be rapidly formed and interlocked by a minimum amount of operations.

A further feature of the invention is to provide a composite container in which the interlocking parts between the metal end closure and the fibre body coact to reinforce the top end of the body and impart added rigidity thereto.

A still further feature of the invention is to interconnect the fibre body of the container to the metal end closure in a manner which will prevent removal and replacement of the end closure without detection, thus discouraging unscrupulous reuse of the container.

Other features of the invention will be apparent as the following specication is read in conjunction with the accompanying drawing, in which:

Figure l is a perspective view of one form of my composite container.

Figure 2 is a detail vertical sectional View on the line 2-2 of Figure 1.

Figure 3 is an enlarged detail vertical sectional view of the vinterlocking parts between the bre body and the metal end closure.

Referring to the drawing by reference characters, the numeral I 0 designates one form of my composite container in its entirety which broadly consists of a bre container body II and a metal top end closure I2. The container ID is shown as round in plan in the drawing, but it will be understood that the samemay be of other shapes in plan if desired, such as oval, elliptical, rectangular, square, or rounded in configuration.

The container body Ill includes an annular side wall I3 made oi' paper, cardboard or other like bre material, and a bottom wall I4 which is secured to the lower end of the side wall in any Well known conventional manner.

The metal top end closure I2 is constructed of relatively thin sheet metal and includes an annular body portion I5 which is concavo-con- Vex in cross section. The blank of metal from which the .end closure I2 is constructed is bent upon itself inwardly of its peripheral edge to provide an annular downwardly bent flange I6 which consists of an inner downwardly bent portion I'I and an outer outwardly bent portion I8,the portions I'I and I8 being disposed in parallel relation and in abutting contact. The bending of the metal to form the double thickness ange I 6 results in the formation of a rounded edge I 9 at the inner end of the said flange. The ilange I6 snugly telescopes within the open top of the annular side wall I I of the contanerbody and is embraced by the side wall I I. The peripheral edge of the metal stock from which the end closure I5 is constructed is bent outwardly from the top of the portion I8 as at 20, the bend between the portions I8 and 2i) being in Contact with the bend between the portion Il and the body I5 so that the annular portion 2B constitutes a continuation of the top surface of the body portion I5. After forming the portion 20, the periphery or" the blank of metal is rolled downwardly and inwardly against the exterior of the side wall I3 to form a channel-bke clinching bead 2|. The peripheral edge of the bead 2| is rolled upwardly and inwardly to provide an upturned annular hook portion 22 which embeds itself in the nbre side wall I3 adjacent the top edge and coacts with the annular flange I6 to tightly secure the end closure I2 to the side wall I3 of the fibre container body II. The annular ange I6 provides a rigid backing during the downward and inward bending of the annular rolled bead 2l.

The body portion I5 of the end closure I2 is provided with an upstanding spout 23 which may be provided with pouring openings 24. A removable closure cap 25 telescopes the spout 23. The contents of the container I0 may be poured through the openings 24 when the cap 24 is removed, and although I have illustrated the container I .as having a perforated pouring spout in the drawing, other conventional forms of discharge openings may be resorted to.

While I have shown and described what I consider to be the preferred embodiment of my invention, it is understood that such changes in construction and design as come `within the scope of the appended claims may be resortedto if desired without departing from the spirit ofthe invention.

Having thus described the invention, what I claim 'as new and desire to secure by 'Letters Patent fof the United States, "is:

1. A composite container comprising .a hollow body having lan open -top fdefined by a fibre side wall of continuous curvalinear form, a metal Atop end closure including an voutwardly bulged body portion of Vconcavo-convex in `cross section and of va size Aand 'shape corresponding to 'that of the side wall -of said bodyat the open top thereof and extending vabove the plane of -the side wall, saidtbody portion being Vldevoid of depressions, a

downwardly extending continuous double wall flange integral with said body portion of a shape and size conforming to the inner side of said side wall and disposed in intimate Contact therewith, and an outwardly, downwardly, and inwardly rolled peripheral bead integral with the body portion and terminating above the plane of the lower edge of said flange and provided with an upturned hook edge in clinching engagement with the outer side of said side wall and acting to press the fibre side wall into sealing engagement with said continuous flange.

2. A composite container comprising a hollow body having an open top defined by a fibre side wall of `curvaliriear form, a metal top end closure including a body portion of a size and shape corresponding to that of the fibre side wall of said body at the Yopen top thereof, a downwardly extending continuous double wall flange integral with said body portion of a shape and size conforming '-to the inner side of said fibre side wall and disposed in intimate contact therewith, and an outwardly, downwardly, and inwardly rolled peripheral bead integral 'with the body portion and terminating above the plane of the lower edge of said flange and provided with an upturned lhook edge in felino-hing engagement with the outer lside of said side wall and acting to press .the `fibre side wall into sealing .engagement with said continuous flange.
